Serial My invention relates to typewriting or like machines and more particularly to the paper feed mechanism of suchmachines.

p The main object of my invention, generally stated, is to provide improved means which are simple in construction and efficient in use for adjustably mounting margin paper feed devices.' a l To the aboveand other endsv which will hereinafter appear, my invention consists in the features of construction, arrangements ofparts and combinations 'ofdevices set forth ter; such for example, as those disclosed'in detail inmy hereinbefo're' mentioned parent inthe following description and particularly pointed out in the appended claims.

Project I ing from the. lower end of the paper finger are plate l 'on the' carriage, as "shown inrdotted a comparatively long sheet metal carrier or slide,- designated as a Whole by the reference numeral 22. This carrier comprises a fiat plate like vertically disposed portion 23 which at its upper edge is provided with rear Wardly extending horizontal projections or lugs 24 bent downward and forward at their free end'syas indicated at 25, to surround the rear edge of and embrace' th'e flange 12 of the supporting bar, as shown in Fig 3, v These extenslons or projections 24am widely-separated, beinglocated at the ends of the platelikebody portion 23 of the carrier .andfleav-' ing a large intervening space between them. A-coiled spring 26 surrounds the pivot rod 20., one end 2 7 of the spring-bearing against the associated paper finger 13, and the'other end 28 hearing against the plate-like member '23 er the associated carrier. The power of this spring is exerted at one'end to "force the member 23 against the front flat face of the supporting bar, whereas the spring at its 7 'carrier' 'where xit is other end exerts its force against the coin- -p'anion paper -finger 13'tomaintain its feed roller 17 a :in "contact with the 4 platen or the paper thereon V V 7 This very simple and inexpensive form of paper finger construction and mounting requires no nice fitting of the slide :or-carrier on its supporting bar andyet enables each rofithe rpaperfingers and itscarrier-to be easily adjusted longitudinally o-fithe platen without any nndue. cramping for Joinding action of i 4 the carrier @OII thebar; such as is formed in many constructions heretofore employed. 7 This freedom for sliding adjustment of the frictionally held "carrier is'a provided, in the presentinstance, notwithstanding the finger piecelby which 'a finger :13 and its-carrier 40 for slide are adjusted along the supporting ba r.,f is located; at a point remote from the 'most convenient-to the foperator;

Theen'd plates '1 and said arms '29, however, "will prevent an accidental displacement of the fingers and their carriers ffrom the'supporting bar when the parts are .in use. a like mannerthe carriers and fingers maybe readily mounted in'place.
